Abstract
A piezoelectric ceramic transducer for ultrasonic toothbrush is improved on the basis of the prior art, which comprises a piezoelectric ceramic plate, metal electrodes and wires thereof which are arranged on the front side and the back side of the piezoelectric ceramic plate, and is characterized in that the piezoelectric ceramic plate is in an elliptic shape, the front metal electrode is adhered with a brass sheet through conductive epoxy-resin glue as part of an electrode, wherein the brass sheet is in an elliptic shape, one end of the brass sheet is extended with a convex lug, and the electrode wire on the back side is welded on the convex lug. The piezoelectric ceramic transducer has reasonable design, high piezoelectric ceramic plate strength and high wire bond firmness, small thickness of a transducer, and is easy to pack.
Description
Technical field:
The utility model relates to a kind of parts of ultrasonic toothbrush device, particularly a kind of piezoelectric ceramic transducer.
Background technology:
As everyone knows, ultrasonic toothbrush is realized by the frequency that ultrasonic vibration produces, and piezoelectric ceramic transducer is the parts that are used for producing ultrasonic vibration.The general structure that is used for the piezoelectric ceramic transducer of ultrasonic toothbrush is that sintering one deck silvery thin layer is distinguished as positive and negative electrode in the piezoelectric ceramic piece of a slice strip, its both sides, directly is connected in the circuit.And head toothbrushes generally all is oval-shaped, and piezoelectric ceramic transducer is installed in the interior cavity of head toothbrushes, because the cavity of head toothbrushes is limited, transducer is after weld on the two sides, and lead-in wire connects inconvenient, and gross thickness is bigger after welding, and is unfavorable for encapsulation and fixing of energy converter; The bad control of piezoelectric ceramic piece thickness, too thick take up room too big, too thin frangible; And transducer commonly used is strip, and is inharmonious with the head toothbrushes cavity shape, also is unfavorable for encapsulation.
Summary of the invention:
In order to overcome the existing defective that the firm degree of piezoelectric ceramic transducer is relatively poor, shape is unreasonable and lead packages is inconvenient, the utility model provides a kind of improved piezoelectric ceramic transducer, can overcome the defective of prior art effectively.
The purpose of this utility model is improved realization on the prior art basis, the metal electrode and the lead thereof that comprise piezoelectric ceramic piece, piezoelectric ceramic piece front and back, the piezoelectric ceramic piece ovalisation that it is characterized in that it, on the positive metal electrode by the gluing part that posts a latten(-tin) as electrode of conductive epoxy resin, said latten(-tin) ovalisation, the one end is extended with lug, and the electrode cable of this face is welded on this lug.During use, the utility model piezoelectric ceramic transducer is contained in the cavity of head toothbrushes, latten(-tin) one side is combined with the one side of cavity, two electrode cables are connected on the ultrasonic circuit of toothbrush and get final product.
The utility model is reasonable in design, the whole ellipse that adopts, consistent with head toothbrushes, be adhesive with the latten(-tin) of an end band lug on the front electrode of piezoelectric ceramic piece, electrode cable is welded on this lug, and piezoelectric ceramic piece intensity and wire-bonds fastness are improved greatly, and electrode pads is in same direction simultaneously, help reducing the thickness of transducer, be convenient to encapsulation.
Description of drawings:
Fig. 1 is that master of the present utility model looks the sectional structure schematic diagram
Fig. 2 is a upward view of the present utility model.
The specific embodiment:
Accompanying drawing has provided the utility model specific embodiment, be elaborated to this use is novel below in conjunction with accompanying drawing: with reference to Fig. 1, shown in Figure 2,1 is piezoelectric ceramic piece among the figure, the front sintering of piezoelectric ceramic piece 1 has metal electrode 3, back side sintering has metal electrode 2, be welded with lead 5 on the metal electrode 2, its piezoelectric ceramic piece 1 ovalisation, be pasted with the part of a latten(-tin) 8 by conductive epoxy resin glue 4 on 3 on the metal electrode of front sintering as electrode, said latten(-tin) 8 ovalisation, the one end is extended with lug 7, and the electrode cable 6 of this face is welded on this lug 7.
